i have a dlna server on one VLAN, and i want to forward the multicast traffic to other VLANs so clients on those VLANs can subscribe to the streams and consume the media. i have a sg300-28, and a linux machine running as a router. the router has IGMPproxy installed and should be able to forward the IGMP multicast traffic, but it seems that both layer 2 and layer 3 need to be in on the effort to get everything working. am i correct in thinking that?
what would i need to configure on the switch to get the dlna multicast traffic sent to ports on other VLANs? do i need both layer 2 and layer 3 to participate in the effort?
thanks in advance.
